A two dimensional computer model of the night-time ionosphere was developed to simulate atmospheric processes acting at mid and high latitude regions. The computational method used was finite element simulation FES of the physical processes rather than a numerical solution of the differential equations governing the ionospheric system. The processes of O and H transport, several chemical reactions and O production due to precipitating energetic electrons were included. The initial neutral and ion profiles were input and the time evolution of the O, H, NO and O2 profiles were simulated using a suitable time step. One dimensional simulations of the winter dayside auroral cusp and night-time Millstone Hill profiles and a two dimensional simulation of the poleward wall of the mid-latitude trough were made.
